TUBULAR CHEEK PTEGE FOR- EOOSEJJEAF 'IJEDGERS- Application filed' Febru'ary 26, I924, SerialNo. 695,219.

To all whom may concern.

Be it known that I, Join: Son-son, a citi'Aen of the United States, residing at the city of Holyoke, in the county of Hamp'den and State of i illassachusetts, have invented certain new and useful -Improvements in Tubular Cheek Pieces for Loose-Leaf Ledger's; and I do declare the following to be a full, clear,-and exact'description oft-he invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in attaching hinge lugs to the-tubular back cheek pieces for loose leaf ledger-sand hasfor its object not only to improve the form of'the hinge lug itself but also to greatly simplify and cheapen as a whole the tubular portions with the hinge lugs secured thereto.

Heretofore the method commonly practiced is to form the lug out of the material of the tube itself, or to weld or rivet the hinge lugs thereto, but the first method.

" is troublesome and expensive since it involves quite a waste of material, and makes it necessary to carry in stock a large assortment of tubes having varying hinge lug spacings, while the second method is likewise objectionable for the reason that if the lug is fastened to the inside of the tube it is liable to interfere with the mechanism contained in the tube, and if it is fastened to the outside of the tube then the remaining portion of the latter must be padded to an extent corresponding to the thickness of the metal used in the lug.

The present improvement has a decided advantage, because the hinge lugs can be manufactured automatically and slidably connected with the ordinary stock tube and spaced as desired, and the construction of the lug prevents the latter from being pushed into or withdrawn from the tube, and since the lug is fastened close to the. inside edge of the tube it does not interfere in any way with the locking mechanism contained in the tube.

Referring to the drawings Figure 1 is a perspective View of the cheek piece tube equipped with "the -*i1nproved hinge eyes.

Figure/2 is a section at the line 2-2 of Figure 1.

Figure 3 is a "detail perspective view of the hinge lugya'nd Figure l isian edge elevation of. the cheek tube recessed to permanently secure the hinge lugs.

Similar numerals of reference denote like parts in the several figures of the drawing.

1 is the usual elongated and slightly *flattened tube member which is located at'the back portion of loose leaf ledger's and these tube members usually carry the'telescopin'g elei'nents'that pass through the usual perforations in the loose leaves, and'also there is usually contained within one or both of the tubes suitable locking mechanism.

This tube is formed from sheet metal bent into shape and with the edges of the metal blank meeting at the outer side portion of the tube.

The numeral 2 is used to designate the hinge lugs generally, and these are formed from sheet metal bent to form an eye por tion 3, and shank 4 and diverging ends 5.

In the construction of these lugs shoulders 6 are formed to extend outwardly from the shank portions of the lug.

In applying these hinge lugs to the tube 1, the meeting edges of the latter are spread and the shank portions 4 introduced therebetween with the shoulders 6 above the tube and pushed along until they are properly located and spaced apart, and when in position between the meeting edges of the tube, the shank portion will be firmly gripped by these edges, the diverging ends 5 will lie against the inner surfaces of the tube, and the shoulders 6 will lie snugly against the upper surfaces of the tube so that it will be clear that the lugs can neither be pulled out of the tube nor can they be driv-v en inwardly.

For quick and convenient spacing of the hinge lugs, one of the meeting edges of the tube may be cut away to provide slight recesses T a trifle longer than the width of the Shanks, so that when the lugs have been pushed between the edges of the tube until they come opposite these recesses, said lugs will be snapped within the recesses by the resiliency of the tube, and will thus be permanently located as against any lateral shifting.

But it is not absolutely necessary to locate the lugs in this manner, since the grip of thetube edges is so strong on the shanks of the lugs that when'the latter are forced to the desired location they will not shift accidentally, andthis accidental shifting is absolutely prohibited because the binding, which is finally glued to the tube, and the hinge plates on the cover that form the complementary portions of the hinge, would prevent this shifting.

The covers and'the manner in which they are equipped to cooperate with the hinge lugs are so well known that any illustration thereof herein would be entirely unnecessar l he tubular members themselves are made of a good grade of resilient steel and lend themselves admirably to the securing of the hinge lugs in themanner hereinbefore explained.

I claim:

1. As an article of manufacture for loose leaf ledgers, a sheet metal tube having an opening along oneedge, and hinge lugs slidably positioned in said opening, said lugs having eye portions and retaining portions that frictionally engage the outside and inside surfaces of said tube.

2. The hereindescribed improvement in the construction of the tubular cheek'portions for the backs of loose leaf 'ledgers, comprising a tubular member formed of sheet metal with the free edges meeting, hinge lugs formed with hinge eyes, shoulders, shanks and diverging ends, the shanks being forced between the meeting edges of the tube and retained in position by the grip of said edges and by said shoulders and diverging ends which embrace the adjacent edges of the tube.

3. The combination of the tube formed of resilient sheet metal with meeting edges, and provided along one of these edges with spaced recesses, of hinge lugs each formed with an eye at its outer end and .with

shoulders, a shank portion and diverging ends, said shank portion being forced between said edges with the latter embraced above and below by said shoulders and di verging ends, this forcing of said shanks causing the latter to engage within said recesses so as to be permanently located therein.

In testimony whereof I afiix my signature hereto.

JOHN SGI-IADE.
